Samosata (Armenian: Շամուշատ, Ancient Greek: Σαμόσατα Samósata, Syriac: ܫܡܝܫܛ šmīšaṭ) was an ancient city on the right (west) bank of the Euphrates whose ruins existed at the modern city of Samsat, Adıyaman Province, Turkey until the site was flooded by the newly constructed Atatürk Dam. The city is sometimes confused with Arsamosata.
Located in southeast Turkey on the upper Euphrates River, it was fortified so as to protect a major crossing point of the river on the east-west trade route. It also served as a station on another route running from Damascus, Palmyra, and Sura up to Lesser Armenia and the Euxine Sea. For a time, the city was called Antiochia in Commagene (Ancient Greek: Αντιόχεια τῆς Κομμαγηνῆς). As Antiochia in Commagene, it served as the capital for the Hellenistic kingdom of Commagene from c. 160 BC until it was surrendered to Rome in 72. A civil metropolis from the days of Emperor Hadrian, Samosata was the home of the Legio VI Ferrata and later Legio XVI Flavia Firma, and the terminus of several military roads.
In February 1098, the emir Baldoukh (Bulduk) of the Turkish Artukid or Ortoqid (Artuklu) dynasty, attacked by Baudouin of Antioch, cut his army to pieces there. In 1114 it was one of the chief quarters of the Muslims hostile to the Count of Edessa, to whom it succumbed, but was recaptured by the Muslims about 1149.
In the Christian martyrology, seven Christian martyrs were crucified in 297 in Samosata for refusing to perform a pagan rite in celebration of the victory of Maximian over the Sassanids: Abibus, Hipparchus, James, Lollian, Paragnus, Philotheus, and Romanus. Saint Daniel the Stylite was born in a village near Samosata; Saint Rabbulas, venerated on 19 February, who lived in the 6th century at Constantinople, was also a native of Samosata. A Notitia Episcopatuum of Antioch in the 6th century mentions Samosata as an autocephalous metropolis (Echos d'Orient, X, 144); at the synod that reinstated Patriarch Photius I of Constantinople (the Photian Council) of 879, the See of Samosata had already been united to that of Amida (Diyarbakır). As in 586 the titular of Amida bears only this title (), it must be concluded that the union took place between the 7th and the 9th centuries. Earlier bishops included Peperius, who attended the Council of Nicaea (325); Saint Eusebius of Samosata, a great opponent of the Arians, killed by an Arian woman (c. 380), honoured on 22 June; Andrew, a vigorous opponent of Cyril of Alexandria and of the Council of Ephesus.
Chabot gives a list of twenty-eight Syrian Miaphysite bishops. The Syrian bishopric probably lapsed in the 12th century. Samosata is included in the Catholic Church's list of titular sees, but no further titular bishops have been appointed for that eastern see since the Second Vatican Council.
Ancient Samosata continues to the present day as the Turkish town of Samsat. The old town of Samsat was submerged in 1989 under the Ataturk Dam. A new town bearing the same name was built for the population dislocated by the sinking of the old town. Modern Samsat is a town of approximately 2000 inhabitants. It is the capital of the district of the same name in the Turkish province of Adıyaman.
